landfills or dumps, hazardous substances
can leak into the groundwater and get into
the food chain, damaging your health and
well-being.
When replacing old appliances with new ones, the retailer
is legally obligated to take back your old appliance for
disposals at least free of charge.

CAUTION ！
Don't apply the cold
air to the body for a
long time.
It will deteriorate your
physical conditions and
cause health problems.
Don’t stand on the
top of the outdoor
unit or place heavy
things on it.
This could cause personal
injuries or damage the unit.
Don’t use the air

NO!
Don’t open the
windows and doors
for long time when
the air conditioner
is running.
Otherwise, the cooling or heating
capacity will be weakened.
Set the suitable
temperature.
If your air
conditioner is not
fitted with a supply
cord and a plug, an
all-pole switch must
be installed in the
fixed wiring and the
distance between
contacts should be
no less than 3.0 mm.
The power supply circuit should have leakage protector and air
switch of which the capacity should be more than 1.5 times of
the maximum current.
Appropriate adjustments of the
setting temperature can prevent
the waste of electricity.
If your air conditioner is permanently connected to the fixed
wiring, a residual current device (RCD) having rated residual
operating current not exceeding 30 mA should be installed in
the fixed wiring.
It is recommended
that the temperature
difference between
indoor and outdoor
temperature
should not be
too large.

Notes for heating
* The fan of the indoor unit will not start running immediately after the heating is
started to avoid blowing out cool air.
* When it is cold and wet outside, the outdoor unit will develop frost over the heat
exchanger which will compromise the heating capacity. This is when the air
conditioner will start defrost.
* During defrost, the air conditioner will stop heating for about 5-12 minutes.
* Vapor may come out from the outdoor unit during defrost. This is not a malfunction,
but a result of fast defrost.
* Heating will resume after defrost is complete.
Notes for turning off
* When the air conditioner is turned off, the main controller will automatically decide
whether to stop immediately or after running for dozens of seconds with lower
frequency and lower air speed.
Notices for use
The conditions of unit can'tnormally run
*Within the temperature range provided in following table, the air conditioner may
stop running and other anomalies may arise.
* When the temperature is too high, the air conditioner may activate the automatic
protection device, so that the air conditioner could be shut down.
* When the temperature is too low, the heat exchanger of the air conditioner may
freeze, leading to water leakage or other malfunction.
* In long-term cooling or dehumidification with a relative humidity of above 80%
(doors and windows are open), there may be water condenses or dripping near
the air outlet.

* If this button is pushed with the unit OFF,
the air conditioner will operate in Auto mode.
* If this button is pushed with the unit ON,
the air conditioner will stop running.
Emergency operation
1. Use up-down swing and left-right swing
buttons on the remote controller to adjust
the airflow direction. Refer to the operation
manual of the remote controller for detail.
2. For models without left-right swing function,
the fins has to be moved manually.

Clean the panel
When the panel of the indoor unit is contaminated, clean it
gently with a wrung towel using tepid water below 45˚C,
and do not remove the panel while cleaning.
Clean the air filter
■Remove the air filter
1. Use both hands to open the panel for an angle from both ends of the panel in
accordance with the direction of the arrow.
2. Release the air filter from the slot and remove it.
● Before the cleaning of the air conditioner, it must be shut down and the
electricity must be cut off for more than 5 minutes, otherwise there might
be the risk of electric shocks.
● Do not wet the air conditioner, which can cause an electric shock. Make
sure not to rinse the air conditioner with water under any circumstances.
● Volatile liquids such as thinner or gasoline will damage the air conditioner
housing, therefore please clean the housing of air conditioner only with soft
dry cloth and damp cloth moistened with neutral detergent.
● In the course of usage, pay attention to cleaning the filter regularly, to
prevent the covering of dust. If the service environment of the air conditioner
is dusty, correspondingly increase the number of times of cleaning. After
removing the filter, do not touch the fin part of the indoor unit with the finger,
so as to avoid scratching it.
Warning
■Clean the Air Filter
Use a vacuum cleaner or water to rinse filter, and
if the filter is very dirty (for example, with greasy dirt),
clean it with warm water (below 45) with mild
detergent dissolved in, and then put the filter in
the shade to dry in the air.
Clean and care

■Mount the Filter
1. Check whether all the air inlets and outlets of the units are unblocked.
2. Check whether there is blocking in the water outlet of the drain pipe and
immediately clean it up if any.
3. Check if the ground wire is reliably grounded.
4. Check whether the remote control batteries are installed and if the power
is sufficient.
5. Check whether there is damage in the mounting bracket of the outdoor unit and,
if any, please contact our local service center.
Check before use
1. Reinstall the dried filter in reverse order of removal, then cover and lock the panel.
Clean and care
* Do not repair the air conditioner by yourself as wrong maintenance may cause electric
shock or fire, please contact the authorized service center and let the professionals
conduct the maintenance. Checking the following items prior to contacting for
maintenance can save your time and money.
Caution
Troubleshooting
Maintain after use
1. Cut off the power source of the air conditioner, turn off the circuit breaker and remove
the batteries from the remote control.
2. Clean the filter and the unit body.
3. Remove the dust and debris from the outdoor unit.
4. Check whether there is damage in the mounting bracket of the outdoor unit and, if
any, please contact our local service center.
Clean the air filter
Remote controller
is not working.
●Is the remote controller out of effective distance to the indoor unit?
●Are there any obstructions between the controller and the
signal receptor? ●Is the battery exhausted?
Indoor unit does not operate
immediately when the air
conditioner is restarted.
There is an unusual smell
blowing from the outlet
after operation is started.
Cooling/Heating
efficiency is not
good.
●Is the set temperature suitable? ●Are the air filters dirty?
●Is the air inlet or outlet obstructed?
●Is indoor fan speed set at low speed?
●Is there any heat source in your room?
Air conditioner can
not operate at all.
●Has the power been shut down? ● Is the wiring loose?
●Is the voltage too high or too low? (measured by professionals)
●Does it reach the set time for start up?
●Did the circuit protection device trip?
If the air conditioner is turned on immediately after it is
turned off, the protective delay switch will delay the
operation for 3 to 5 minutes.
The air conditioner itself does not have undesirable
odor. If there is odor, it may be due to accumulation
of the odor in the environment. Please clean the air
filter or activate the cleaning function.
There is sound of running
water during the running
of air conditioner.
Sometimes the "hissing" sound of running water
can be heard. This is the sound of the flow of the
refrigerant, not a malfunction.
A slight "click" sound is
heard at the of start-up or
shut-down.
Due to temperature changes, panel and other parts
will swell, causing the sound of friction. This is normal,
not a fault.
During the cooling operation,
the indoor unit outlet
sometimes will blow out mist.
This is because the indoor air is cooled rapidly. After it
runs for some time, the indoor temperature and
humidity will be reduced and the mist will disappear.
▲Shrill sound is heard or unpleasant odor is emitted during the operation.
▲There is an abnormal heat in power supply cord and power plug.
▲Accidentally pour impurities or water into the machine or the remote control.
▲Air switch or protection switch often breaks.
Immediately stop all operations and cut off the power supply ,
contact our local Service Center in following situations.
